349490 Get HTML AND Text in 1 Email

I need an editable template, I suppose in html, to be sent through email, where if the receiving email client is HTML-capable, it displays the HTML properly, but if the recipient has a non-HTML email client (text only) the message will properly display just the text? The template should be easily editable by me, both in the html portion and text portion, with clear markers or "boundaries" so I don't mess up anything important. I would probably use Dreamweaver to edit the html portion. This shouldn't be an issue, but this template or html is to work with a php autoresponder script (not part of this project), probably using the server's "sendmail" function, or similar. If you can provide a bid HERE for JUST the template that would reliably work for almost all email clients, properly displaying html, even with images, as well as plain text for text only clients, then please bid HERE on this project (your comments to assure me of compatibility will be appreciated and considered). I have another job posted for an auto-responder script (project# 1252446565). If you can include the ABOVE template AND supply the auto-responder as described on that project, then please do NOT bid here, but BID over on that project (# 1252446565 "simple autoresponder script") and describe in the bid that you can supply this template as well. Thanks!
